New eco-friendly proposal for the crystallization of beet raw juice

Abstract In the past years we evaluated different strategies with the aim of eliminating completely from the beet sugar factory, the traditional calco-carbonic purification process taking into account the well-known problems related to the utilization of lime and the production of carbonation sludge. To complete the picture of the possible solutions to be adopted for the elimination of the traditional purification process, we tested and evaluated in laboratory and in pilot plants a new eco-friendly proposal. The results obtained, as well as the proposed flow-sheet and some economic evaluations, are presented and discussed.
